To find:

\int (x^{x})^{x}(2xlogx+x)dx

Step-by-step explanation:

Let, (x^{x})^{x}=z

\Rightarrow x^{x^{2}}=z

Taking log in both sides, we get

\quad log(x^{x^{2}})=logz

\Rightarrow x^{2}logx=logz

Taking differentials, we get

\quad d(x^{2}logx)=d(logz)

\Rightarrow (2xlogx+x)dx=\frac{dz}{z}

Now, \int (x^{x})^{x}(2xlogx+x)dx

=\int z\frac{dz}{z}

=\int dz

=z+c where c= integral constant

=(x^{x})^{x}+c

This is the required integral.

Answer:

\int (x^{x})^{x}(2xlogx+x)dx=(x^{x})^{x}+c where c is integral constant.
